Chevy to bring new engines for this weekend in Toronto

INDIANAPOLIS — There were rumors in the paddock for the last NTT INDYCAR Series race on the season at the Mid-Ohio Sports Car Course that concerns were growing for engine failures. See, these engines were installed for the Indy 500 back on May 29 and there were nearing their mileage limit.

Would a 80 degree day in Ohio during early July cost some teams motors or reliability problems? It came up even more when both Arrow McLaren SP cars had mechanical failures. A pair of AJ Foyt Racing Chevy’s did too.

What’s the concern moving forward?

Well, Chevy found that 1 of the McLaren cars was on their end, the other not. The issue from Pato O’Ward’s car in Road America was on their end too. Was a pattern surfacing?

“Chevy obviously does a big investigation into what happened,” Will Power said on Wednesday. “Usually a failure creates — it doesn’t happen twice, put it that way. I don’t know the findings of their investigation. I know one of them was not a Chevy issue.”

Also, Power noted that all the Chevy teams are getting fresh motors for Sunday’s Honda Indy Toronto (3 p.m. ET, Peacock, INDYCAR Radio Network) too.

“Yeah, obviously always concerned when you see that. I will say that all the Chevys are switching out engines because they’re all up on mileage for this race,” he noted. They are all on new engines.”

Chevy has taken 7 race winning trophies in 9 races run this year and is eyeing an 8th in 10 starts this weekend. They’re a perfect 3-for-3 on street courses in general too.
